The highest temperatures in Chiba are recorded in August, with averages reaching a high of 29.8°C (85.6°F) and a low of 24.8°C (76.6°F).

Heat index

The heat index for August is evaluated at a very hot 37°C (98.6°F). Exercise increased caution, heat cramps and heat exhaustion are potential hazards. Continuous activity could lead to heatstroke.
Always consider that heat index estimations are for light winds and places in the shade. Heat index values may rise by up to 15 Fahrenheit (8 Celsius) degrees when exposed to direct sunlight.
Note: The heat index, also known as 'feels like' or 'apparent temperature', is achieved by amalgamating air temperature with the relative humidity readings. Elements such as metabolic variations, being pregnant, and physical activity can impact one's weather perception. Take note that direct exposure to the sun can increase the felt temperature, possibly adding 15 Fahrenheit (8 Celsius) degrees to the heat index. Heat index values remain especially vital for babies and toddlers. Young individuals are generally in more danger than adults due to their lower capacity to sweat. Moreover, their large skin surface in relation to their small bodies and the increased heat generation from their activities makes them more vulnerable.
One way the human body deals with excessive warmth is by perspiring and allowing sweat to evaporate. Higher relative humidity impedes evaporation, thus reducing heat dispersion from the body, culminating in a sensation of overheating. Exceeding the body's heat disposal threshold results in a rise in body temperature and potential thermal disorders.

Ward off overexposure. Defence against solar harm is crucial. Limit your exposure to the sun's UV radiation, which is strongest between 10 a.m. and 4 p.m., and note that parasols or canopies may not provide full sun protection. Experience reduced UV exposure by about half when donning a wide-brim hat. Attention! UV strength is notably upped by the reflection of sand and water.
